Abstract

A diaphragm supporting frame member (1) of paper is formed by a paper making using liquid paper material as a raw material, and a center hole for a voice coil and an air pressure release hole (1a) for discharging into the outside the air pressure in the rear by the vibration of the diaphragm are formed during the paper making, the frame member (1) of paper being used to produce a speaker device.
